A “New South” has emerged over the past several
decades, forged by Hispanic immigration, urbanization,

Field Note
Montgomery, Alabama
Located in a predominately African American neighborhood in Montgom-
ery, Alabama, the street intersection of Jeff Davis and Rosa Parks is sym-
bolic of the debates and disputes in the American South over how the
past is to be commemorated on the region’s landscape. The Civil War and
civil rights movement are the two most important events in the history of
the region. The street names commemorate Montgomery’s central role in
both eras, and they do so in the same public space. Montgomery was the
site of the first capital of the Confederacy in 1861 while Jefferson Davis
was president. The Alabama capital was also the site of the 1955–1956
Montgomery bus boycott that launched the civil rights movement. The Figure 1.21
boycott was sparked by Rosa Parks’s arrest after she refused to give up her
seat on a city bus when ordered to do so by a white person. Most of my
research examines the politics of how the region’s white and African
Americans portray these separate heroic eras within the region’s public spaces, ranging from support for and against flying
the Confederate flag to disputes over placing statues and murals honoring the Civil War and the civil rights movement on
the South’s landscape.

Summary
Our study of human geography will analyze people and places and explain how they
interact across space and time to create our world. Chapters 2 and 3 lay the basis for
our study of human geography by looking at where people live. Chapters 4–7 focus on
aspects of culture and how people use culture and identity to make sense of themselves
in their world. The remaining chapters examine how people have created a world in
which they function economically, politically, and socially, and how their activities in
those realms re-create themselves and their world.

The words wafted in the air as my colleague and I took a minute to process them.
We were in Shanghai, China, visiting with a Chinese student who had spent a
semester at our small college in a town of 26,000 in rural South Dakota. My col-
league had asked the student what he missed most about our small town of
Aberdeen. He replied without hesitating, “Basic infrastructure.”
I thought about brand-new subway lines in Shanghai and Beijing, new airports
throughout China, and high-speed trains being built to connect China’s cities. I
visualized the miles of gleaming new concrete we had driven on that afternoon on
the ring highway on the outskirts of Shanghai (Fig. 2.1) and the empty fields where
houses or other buildings had been leveled to make room for new high-density
housing, more concrete, and more infrastructure. Shanghai’s metro system only

dates to 1995. Shanghai now has the longest metro system on Earth—a system
capable of transporting 5 million people a day. I thought about the lack of public
transportation in my small town. I remembered that in 2010, China committed to
spend an additional $1 trillion on urban infrastructure by 2015. I considered the
words United States President Barack Obama used as he described, enviously, the
infrastructure in China, “their ports, their train systems their airports are all vastly
superior to us now.”
I looked at the student and said, “Basic infrastructure? But you have better
subway lines, high-speed railroads, roads, and airports than we do in the States.”
“Yes,” he said, “But I don’t have hot water.”
A 2010 report in Foreign Policy agreed, “China’s biggest urban challenge may
be water; already, it has little to spare. Some 70 percent of water use today traces
back to agriculture, but demand from urban consumers and commercial enter-
prise is on the rise. Even if the sheer amount of water isn’t the problem, location
will be; the country will need to spend more than $120 billion on water systems in
the coming years to transport, store, and manage supplies.” A graduate student in
Beijing reiterated the water problem in China’s cities. Her dormitory houses about
1000 students, but they all must walk out of the building to a central facility to
shower, and she reported that they are only allowed to shower between 2 and
4 PM or between 9 and 11 PM.
China’s population of 1.34 billion people has been migrating to cities in droves
since economic reforms began in 1978. In 2011, the population of the world hit
7 billion people, with rising populations in China and India accounting for 40 per-
cent of the population growth. China has undergone incredibly rapid expansion in
its mining and manufacturing sectors, resulting in economic growth rates that are
often at 10 percent a year. But rapid economic growth took its toll on water quality
in China, which exacerbates water shortages in the country.
Providing services for 1.34 billion people is no small feat. Even though
demographers now predict China’s population will stabilize at 1.4 billion by 2025
and begin to decline after that, shifts in the composition of China’s population
will continue to challenge the provision of basic infrastructure to the country’s
people.
Southern, coastal China has a moist climate, much like the southeastern
United States, but the climate in northern China is drier. With only 7% of the
world’s fresh water supply, China has an uphill battle in providing water
resources to 1.34 billion people. This challenge is exacerbated by the fact that
southern China has 80% of the country’s water (Foreign Policy, 2011). To remedy
the imbalance, China is now building a $60 billion canal system called the
South-North Water Transfer Project that will include three different routes to
divert water from the Yangtze River in southern China to the cities in the north
(Fig. 2.2).
In this chapter, we examine the distribution of the world’s population at sev-
eral scales in order to understand where people live and why they live where they
do. We also look into the continued growth of global population, noting that
growth rates vary quite widely across our planet. Even as population growth in the
wealthier core slows down to near (or below!) zero, it continues in the less wealthy
periphery, in some countries at rates far above the global average. No such discus-
sion would be complete without consideration of the health conditions prevailing
across the world: health, well-being, and population growth tend to be closely
related. And we will study the role of governments in their efforts to control the
process.

Key Questions For Chapter 2
1. Where in the world do people live and why?
2. Why do populations rise or fall in particular places?
3. Why does population composition matter?
4. How does the geography of health influence population dynamics?
5. How do governments affect population change?

density and physiologic density, the total number of
people stays the same, and the only number that
changes in calculating each is the amount of land. The
difference in arithmetic density and physiologic den-
sity for a single country reveals the proportion of arable
land to all land. In the case of Ukraine, the physiologic
density is 1.68 times as high as the arithmetic density
because 1 out of every 1.68 acres of land in Ukraine

India has much more arable land per person than China.

People are not distributed evenly across the world or
within a country. One-third of the world’s population
lives in China and India. Yet, each country has large
expanses of land (the Himalayas in India and a vast inte-
rior desert in China) where people are absent or sparsely
distributed. In addition to studying population densi-
ties, geographers study population distributions—
descriptions of locations on the Earth’s surface where
individuals or groups (depending on the scale) live.
Geographers often represent population distributions
on dot maps, in which one dot represents a certain
number of a population. At the local scale, a dot map
of population can show each individual farm in a
sparsely populated rural area. At the global scale, the
data are much more generalized. In the following sec-
tion of this chapter, we study world population distri-
bution and density.
